Improvement in strikers for spring locks and latches



UNITED STATES PATENT OFFICE..

WARREN H. TAYLOR, OF STAMFORD, CONNECTICUT, ASSIGNOR TO THE YALE LOCKMANUFACTURING COMPANY, OF SAME PLACE,

IMPROVEMENT IN STRIKERS FOR SPRING LOCKS AND LATCHES.

Specification forming part of Letters Patent No. 201,572, dated March19, 1878 application filed March 8, 1878.

To all whom t may concern-:

Be it known that I, WARREN E. TAYLOR, of Stamford, in the county ofFairfield and State of Connecticut, have invented an Improvement inStrikers for Spring Locks and Latches, of which the following is aspecification:

My invention relates particularly to that class of strikers used inconnection with mortise-locks, in which the striker-plate or keeper islet into the jamb of the door, and the flange or nose thereof extendsoutward to the edge of the jamb, to be struck by the beveled spring boltor latch.

The diiculty with this class of strikers heretofore has been that, whilethe impact of the beveled edge of the bolt or latch upon the strikertended to retract the bolt or latch, it also tended to force it back ona line at right angles to its line of retraction against its bearing inthe lock-case, thus causing the bolt to bind, and rendering the doordiflicult to latch. Where a roller has been used, it has been mounteddirectly upon the ordinary striker-plate, and has been therefore in- Ycapable of adjustment to suit varying positions of the boltor latch indoors of diiierent thicknesses.

My invention is designed to overcome these objections; and consists inproviding and combining with the ordinary striker-plate a separateplate, carrying a striker-roller, which can be readily adj usted inconnection with the striker-plate or keeper.

In the accompanying drawings7 Figure 1 is a perspective view of theordinary striker or keeper plate detached; Fig. 2, a similar view of theadjustable plate, carrying the strikerroller; and Fig. 3 is a sectionalview through the door, striker, and jamb, showing its mode ofapplication and operation.

An adjustable plate, A, adapted to be applied to the jamb of a door,back of the ordinary striker or keeper plate B, is formed substantiallyas shown, so as not to obstruct the recessb in the keeper-plate B forthe reception of the bolt or latch, and has upon its outer edge astriker-roller, a, which turns upon a pin mounted in suitable lugs a a.

The striker or keeper plate B is of the usual form, the nose or ange b1being made sufficiently long to accommodate itself to the thickestordinary doors; andk in practice it may be readily cnt o by the workmanapplying it, to adapt it to doors of varying thicknesses.

In the present instance the adjustable plate A is shown as let into thejamb of the door, so that its arms or ends C C rest upon the screws D D,which secure the plate B in position; but it is obvious that it may beso let into the jamb as to bring the roller ainto any desired positionrelative to the edge ofthe jamb.

The nose or ange b1 of the plate B may be slightly beveled or cut away,as shown at b2, to avoid any possibility of its interfering with thefree rotation of the strikerroller a. This plate B is let into the j ambover the Vadjustable plate A, and, being screwed down upon plate A,holds it securely in place.

In closing the door the beveled edge of the -bolt or latch strikesagainst the roller, which rolls upon its face, and thus greatlyfacilitates the latching of the door.

Instead of the plate A being secured in place, as above described, itmay obviously be connected with the keeper plate B by means of groovesand ways, or slotted screwholes, or in any other well-known way, so asto be readily adjustable to accommodate doors of any thickness.

It will thus be seen that by my invention I secure a striker that can beeasily adjusted, so as to be used upon almost any jamb in connectionwith a mortise-lock ina door of almost any thickness, instead of havingto use, as heretofore, a particular size of striker 'for each thicknessof door.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. As a new article of manufacture, an adjustable plate provided with astriker-roller, adapted to be applied to the jamb of a door, inconnection with an ordinary striker plate or keeper, substantially asdescribed.

2. The combination of an adjustable plate provided with a striker-rollerand a keeperplate, substantially as described.

In testimony whereof I have hereunto subscribed my name. V
